{"version":"1.0","type":"rich","title":"act6_tut4","description":"This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for 31 car makes. Each bubble's x-position maps to horsepower, the y-position to torque, and the bubble's radius encodes highway MPG. The color of each bubble is assigned per make using `d3.interpolateTurbo` and `d3.scaleOrdinal`. Hovering reveals a tooltip with the make name. The chart is rendered with D3.js v7 in SVG, including axes, a size legend for MPG, and a color legend. Data is loaded from a CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/425d51292529422cb56af478299fd0b6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
